GlassFish 3.1 offers cluster support

Oracle has released version 3.1 of its GlassFish application server. The open source version of the Java EE 6 reference implementation includes mature cluster capabilities – up to 100 instances per domain, and cluster administration options (e.g. SSH provisioning and centralised control). Using plug-ins, the new version also has tool support for Java development environments NetBeans and Eclipse, to be followed shortly by Oracle's Enterprise Pack for Eclipse.

GlassFish now implements OSGi implementation Apache Felix 3.0.5, resulting in better OSGi support. Other notable features of the latest version of GlassFish include improved embedded and RESTful APIs, a Maven plug-in and detection of JDBC statement vulnerabilities.

It also includes Oracle's GlassFish Server, a commercial version of the application server which offers additional server control mechanisms. According to the revised GlassFish roadmap, version 3.2 will be released at the turn of the year. GlassFish 4.0, which is set to implement Java Enterprise Edition version 7, is scheduled for release in 2012.

Glassfish is available to download , and the source code is released under a dual licence "consisting of the Common Development and Distribution License (CDDL) v1.0 and GNU General Public License (GPL) v2."
